I'm getting a GT 1150rpm today and also a Sflex F. And I also have some Yate SL from petras. I'm going to test them out today. But listening to the videos the GT is still king. And it has an easy sound on the ears.

It seems that fans have some volts they don't like. They can even go down in noise if you give them higher volts.

Do you have some lower speed GT's you going to run later? I'm really interested in them!
